Hello.
How would a 91 560 act if ecu was faulty or even disconnected. Specificly when starting cold. Have checked power to cold start injector with noid lamp its good, set lambda at operating temperature to 50% the only other things I haven't done is check the integrity of the fuel accumilator also haven't been able to check fuel pressure. If I can remove the hose from the nipple on the back side of the F/A and plug it, put a clear hose on there and cycle the I/Switch to prime the system and see if any fuel is leaking out of the nipple past the diaphragm would that save me having to check the fuel pressure.
Any and all thoughts on the matter would be welcome. The car is very hard to start in the AM even after cycling the key several times. Once started runs like a top everything normal.
Any and all thoughts on the matter would be welcome.
Thanks.
